SPECIFICATION forming part of Letters Patent 1}]0. 610,240, datedSeptember 6, 1898. Application filed November 5,1897. seria no. 657,540.(No ates To all whom it may concern.-

Be it known'that I, JOHANNES OBERLE, a subject of the Emperor ofGermany, and a resident of Gernsbach, in the Empire of Germany, haveinvented certain new and useful Improvements in Bells, of which thefollowing is a full, clear, and exact description.

The present invention consists of an improved construction of bell,according to which the striking mechanism is so arranged that a longslow pressure applied to the lever shall produce a continued successionof vibrations of the hammer against the bell.

In order to render the present specification more easilyintelligible,reference is had to the accompanying drawings, inwhichsimilar letters and figures of reference denote similar parts throughoutthe several views.

Figure 1 is a side elevation of the device with the bell in section;Fig. 2, an end elevation of thestriking mechanism with the bell insection; Fig. 3, aplan of Fig. 1 with the bell removed, and Fig. 4. adetail side elevation of the ratchet-coupling device.

The hell 9 is suitably mounted in a housing or frame of any usualconstruction, and the hammer 0 is caused to vibrate against the saidbell by means of a ratchet-like wheel m, mounted in the frame of thebell and 0perated by means of the lever h and gearing, as hereinafterset forth. The lever his pivoted to a standard I), and has its forwardend connected by a pin-and-slot connection 0 to the lower end of a rack.2", which is guided by and adapted to slide on guide-bars '5 and 2. Atthe opposite side of the standard I) a spring f is arranged to normallykeep the rack in its lowest position. The rack z engages a pinion 5,mounted in the frame, and keyed to the same shaft as the pinion sis aratchet-wheel 6. Loose 0n the same shaft and in proximity to theratchet-wheel e is a larger gearo", to the adapted to engage theratchet-wheel and cow ple thesame to the gear r during one movement ofthe lever Jz, while at the back movement of the samethe pawls will slideover the teeth of the wheel e and the bell will not be operated. Thegear 1" engages a smaller gear or pinion o, fast on a shaft which alsocarries the wheel m, and this wheel vibrates the hammer o by means ofthe escapement (I, attached to the latter and against which the teeth ofthe said wheel impinge.

The operation will be evident from the foregoing description. If thelever is slowly depressed,the rack z sets the gearing in motion and thewheel m causes the hammer to vibrate against the bell continuously for aconsiderable time, viz., until the lever It has been depressed as far asit can go. On releasing the lever h the parts will be returned to theirinitial position by means of the spring f; but

the bell will not be sounded during the movement back, owing to the factthat the pawls slide over the teeth of the ratchet-wheel 6.

By inserting more gearing the continued ringing may be prolonged stillmore, as will be evident.

I claim as my invention The combination of a lever h pivoted to a.

standard I), a bell g mounted in proximity to said lever, a rack zmounted underneath the bell and means for guiding the same vertically,pin-and-slot connection between said lever and rack, a pinion s toengage said rack and ratchet-wheel and pawl connection between saidpinion and a gear loosely mounted in proximity thereto, a ratchet-likewheel mounted in proximity to said gear and a pin-.

ion to rotate with said ratchet-like wheel and engage said gear, apivotally-mounted hammer 0 having escapement d to engage theratchet-like wheelm and a spring f to retain the operating-lever h inits initial position substantially as described. In testimony whereof Ihave signed my name to this specification in the presence of twosubscribing witnesses.

Y J OHANNES OBERLE.
